A giant exoplanet orbiting a very low-mass star challenges planet formation models
J. C. Morales, A. J. Mustill, I. Ribas +179
Statistical analyses from exoplanet surveys around low-mass stars indicate that super-Earth and Neptune-mass planets are more frequent than gas giants around such stars, in agreeme…
A comprehensive study of NGC 2345, a young open cluster with a low metallicity
J. Alonso-Santiago, I. Negueruela, A. Marco +3
NGC 2345 is a young open cluster hosting seven blue and red supergiants, low metallicity and a high fraction of Be stars which makes it a privileged laboratory to study stellar evo…
StePar: an automatic code to infer stellar atmospheric parameters
H. M. Tabernero, E. Marfil, D. Montes +1
Context: StePar is an automatic code written in Python 3.X designed to compute the stellar atmospheric parameters Teff, log(g), [Fe/H], and of FGK-type stars by means of the EW met…
The CARMENES search for exoplanets around M dwarfs. Two temperate Earth-mass planet candidates around Teegarden's Star
M. Zechmeister, S. Dreizler, I. Ribas +182
Context. Teegarden's Star is the brightest and one of the nearest ultra-cool dwarfs in the solar neighbourhood. For its late spectral type (M7.0V), the star shows relatively little…
The CARMENES search for exoplanets around M dwarfs: Different roads to radii and masses of the target stars
Andreas Schweitzer, V. M. Passegger, C. Cifuentes +28
We determine the radii and masses of 293 nearby, bright M dwarfs of the CARMENES survey. This is the first time that such a large and homogeneous high-resolution (R>80 000) spectro…
